In a randomized block ANOVA, why is there no test for interaction?
Step by step
Solved in 2 steps
- What does an interaction in two-way ANOVA mean? (I’m not asking what it looks like graphically, but what does it mean?)In Randomized Block Design ANOVA, when should we perform Tukey-Kramer multiple comparison analyses, and why?If the results of a two-factor ANOVA show no main effect for factor A but show a significant interaction, then the results indicate that factor A has no effect on the subjects' scores. True or False
- In randomized block ANOVA, what is meant when we say thata. there is a treatment effect?b. there is a blocking effect?For an analysis of variance (ANOVA) comparing four treatment conditions, dfbetween = 3. True FalseIn ANOVA, what will be the conclusion when the means of the between groups vary from within groups? a.Accept the null hypothesis b.Reject the null hypothesis c.Conduct main effects d.Conduct interaction effects
- for a one factor anova comparing four treamtnets, what is the null hypothesisExplain how the average causal effect for a given population can be estimated by using an ideal randomized controlled experiment?An investigator reviewed the medical records of 200 children seen for care at Boston Medical Center in the past year who were between the ages 8 and 12 and identified 40 children with asthma. He also identified 40 children of the same ages who were free of asthma. Each child and their family were interviewed to assess whether there might be an association between certain environmental factors such as exposure to second-hand smoke. This study is an example of a: A) Case-Control Study B) Crossover Trial C) Cohort Study D) Randomized Control Trial
